[ Background Art ]

The intensity and time of the human body receiving the ultraviolet light are key parameters of skin health. Meanwhile, ultraviolet radiation can cause the surface temperature of human skin to rise rapidly, but the core temperature of human body rises slightly. The current ultraviolet detection method does not have continuous monitoring capability, can not accurately detect the core body temperature of the human body, and can not provide effective protection reminding for users.

[ Invention ]

Therefore, the embodiment of the invention provides a protection prompting method and electronic equipment, which have the continuous monitoring capability and accurately detect the core body temperature of a human body, and provide effective protection prompt for users.

And carrying out protection prompt on the user according to the ultraviolet radiation and the core body temperature. According to the embodiment of the invention, the ultraviolet radiation quantity and the core body temperature received by the user can be continuously monitored in an ultraviolet radiation scene, and effective protection reminding is provided for the user according to the ultraviolet radiation quantity and the core body temperature.

With reference to the first aspect, in certain implementations of the first aspect, obtaining ultraviolet radiation from the ultraviolet light intensity includes:

And carrying out accumulated summation on the ultraviolet light intensity to obtain the ultraviolet radiation. In actual monitoring, the ultraviolet sensor is called once every interval time to acquire ultraviolet intensity, so that the ultraviolet radiation quantity calculated by adopting an accumulated summation mode is more accurate according to the ultraviolet intensity and the interval time.

With reference to the first aspect, in certain implementation manners of the first aspect, the obtaining the core body temperature of the user according to the ultraviolet light intensity, the first temperature and the second temperature includes:

And if the ultraviolet light intensity is greater than or equal to the first threshold value, obtaining the core body temperature of the user according to the ultraviolet light intensity, the first temperature and the second temperature. The embodiment of the invention determines the current ultraviolet radiation degree by utilizing the ultraviolet light intensity, and when the ultraviolet light intensity is smaller than the first threshold value, the user is indicated to be in a low ultraviolet radiation scene, and the influence of the ultraviolet light on the core body temperature of the user is smaller. Therefore, the core body temperature can be calculated without considering the ultraviolet intensity, and only the ambient temperature and the skin temperature of the user are considered. When the ultraviolet light intensity is greater than or equal to a first threshold, the user is indicated to be in a high ultraviolet radiation scene, and the ultraviolet light has a larger influence on the core body temperature of the user. The intensity of uv light needs to be considered in calculating the core body temperature. Therefore, the ultraviolet intensity is compared with the first threshold value, and the detection models of the core body temperature are respectively built according to the radiation intensity scenes, so that the core body temperature detection accuracy can be effectively improved. The calculation method of the core body temperature under different ultraviolet radiation scenes is realized.

And if the core temperature is greater than the fourth threshold, prompting the user to pay attention to prevent heatstroke according to the core temperature. In the embodiment of the invention, if the core body temperature is greater than or equal to the third threshold value and less than or equal to the fourth threshold value, the core body temperature of the user is in the normal body temperature range, and no temperature protection prompt is performed; if the core body temperature is smaller than a third threshold value, indicating that the core body temperature of the user is smaller than the lowest normal body temperature, and prompting the user to pay attention to the temperature loss protection according to the core body temperature; if the core temperature is greater than the fourth threshold, indicating that the core body temperature of the user is greater than the highest normal body temperature, and prompting the user to pay attention to prevent heatstroke according to the core body temperature.

In the embodiment of the invention, taking an Android system with a layered architecture as an example, a software structure of the electronic device 100 is illustrated.

Fig. 2 is a software configuration block diagram of the electronic device 100 according to the embodiment of the present invention.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun rows (Android runtime) and system libraries, and a kernel layer, respectively.

The application layer may include a series of application packages.

As shown in fig. 2, the application package may include applications for cameras, gallery, calendar, phone calls, maps, navigation, WLAN, bluetooth, music, video, short messages, etc.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for the application of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 2, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc.

The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture.

The telephony manager is used to provide the communication functions of the electronic device 100. Such as the management of call status (including on, hung-up, etc.).

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android run time includes a core library and virtual machines. Android runtime is responsible for scheduling and management of the android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), 2D graphics engines (e.g., SGL), etc.

The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The workflow of the electronic device 100 software and hardware is illustrated below in connection with capturing a photo scene.

When touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into the original input event (including information such as touch coordinates, time stamp of touch operation, etc.). The original input event is stored at the kernel layer. The application framework layer acquires an original input event from the kernel layer, and identifies a control corresponding to the input event. Taking the touch operation as a touch click operation, taking a control corresponding to the click operation as an example of a control of a camera application icon, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera driver by calling a kernel layer, and captures a still image or video by the camera 193.

Ultraviolet (UV) rays in sunlight have promoting effect on human health, can sterilize, promote vitamin D production, and can improve nerve, endocrine, immune system, etc.

However, excessive ultraviolet radiation causes Matrix Metalloproteinases (MMPs) in the skin to deactivate collagen and damage cells, thus causing irreversible effects. Continuous irradiation can cause skin darkening, sunburn, dry pain, itching, desquamation, premature aging, and even skin cancer.

The intensity and time of the human body irradiated by ultraviolet light are key parameters of skin health; by monitoring the intensity and time of ultraviolet received by human bodies, particularly the face, and integrating physiological parameters such as ambient temperature, body temperature and the like, the ultraviolet protection/irradiation suggestion and guidance are provided, and the ultraviolet protection/irradiation suggestion and guidance method has important significance for skin health of human bodies, particularly skin care of female groups.

Currently, weather APP in electronic devices can provide an ultraviolet index. For example, weather APP shows an ultraviolet index of 2. Therefore, the weather APP only has a prompt function, the intensity and time of ultraviolet radiation actually accepted by the user cannot be monitored, and the frequency of the user checking the weather APP is low and is not perceived.

Currently, hand-held detectors have ultraviolet radiation detection capabilities. However, the handheld detector can only perform single-point measurement, does not have wearing capability, and cannot prompt a user in time according to the ultraviolet radiation quantity actually accepted by the user.

There is also a nail sticker (built-in ultraviolet sensor) for monitoring ultraviolet radiation, which is placed on a user's nail to detect ultraviolet rays. Because of the frequent activities of the user's hands, occlusion problems are likely to occur (e.g., the user places his hands in clothing), which cannot characterize the ultraviolet radiation actually received by the human body, especially the face. And the physiological signals at the nails are less, the nails are far away from the core of the human body, and the key parameters related to radiation such as body temperature and the like are absent.

In summary, the current ultraviolet detection method does not have the capability of continuously monitoring the intensity of ultraviolet radiation received by the face of the human body, can not accurately detect the core body temperature of the human body under the condition of high-intensity ultraviolet radiation, can not timely and effectively inform the user of ultraviolet protection and temperature protection, and can not provide effective protection reminding for the user.

Based on the technical problems, the embodiment of the invention provides electronic equipment, which comprises wearable equipment capable of contacting the skin of a user. For example, the wearable device includes smart glasses, smart watches, or smart headphones, among others. The embodiment of the invention is suitable for the scenes of ultraviolet radiation monitoring and core body temperature monitoring, and the wearable equipment is used for monitoring the ultraviolet radiation and body temperature change of the user, so that the user is timely reminded to make protection, the skin health of the user is protected, and the risks such as heatstroke are avoided.

Taking smart glasses as an example, fig. 3 is a schematic diagram of an electronic device according to an embodiment of the present invention. As shown in fig. 3, the smart glasses 20 include a front panel 21 and two legs 22, and the front panel 21 and the legs 22 are movably connected by a hinge 23. The front panel 21 includes two spectacle lenses. One of the temples 22 is internally provided with a main board PCB24, and the front panel 21 is internally provided with a sub-board PCB25 at a position close to the one of the temples 22. The main board PCB24 and the sub-board PCB25 are electrically connected by an FPC flexible flat cable 26. The FPC flexible flat cable 26 passes through the temple 22 and the hinge 23 (hinge) in the frame. A third sensor 241, a processor & bluetooth 242 and a speaker 243 are provided on the main board PCB 24. The sub-board PCB25 is provided with a first sensor 251 and a second sensor 252.

The first sensor 251 is an ultraviolet sensor for collecting ultraviolet light intensity (also referred to as ultraviolet index). When the user wears the smart glasses 20, since the first sensor 251 is located on the front panel of the smart glasses 20, the first sensor 251 can collect the intensity of ultraviolet light received by the user's face.

The second sensor 252 is a temperature sensor, and is disposed on the outer side of the smart glasses 20, and is used for collecting the first temperature. The first temperature is ambient temperature.

The third sensor 241 is a temperature sensor, and is disposed inside the temple 22, and can contact the skin of the user to collect the second temperature. The second temperature is a skin temperature of the user.

The processor is configured to obtain the intensity of ultraviolet light collected by the first sensor 251, the first temperature collected by the second sensor 252, and the second temperature collected by the third sensor 241; obtaining ultraviolet radiation according to the ultraviolet intensity; obtaining the core body temperature of the user according to the ultraviolet light intensity, the first temperature and the second temperature; and carrying out protection prompt on the user according to the ultraviolet radiation and the core body temperature.

Bluetooth is used to establish bluetooth connections with other electronic devices.

Speaker 243 is used to play the voice of the guard prompt.

As an alternative, the processor is specifically configured to integrate the intensity of the ultraviolet light to obtain the amount of ultraviolet radiation. The user can continuously receive ultraviolet radiation in an ultraviolet radiation scene, and the ultraviolet radiation U continuously received by the user is calculated by adopting a method of integrating the ultraviolet intensity Uv detected by an ultraviolet sensor:

U＝∫U_vdt

As a further alternative, the processor is specifically configured to cumulatively sum the ultraviolet light intensities to obtain the ultraviolet radiation. In actual monitoring, the ultraviolet sensor is called once at every interval t _i, the detected ultraviolet intensity is U _Vi, and the cumulative summation mode is adopted for calculation:

U＝∑U_vit_i

The processor is specifically configured to acquire the ultraviolet light intensity acquired by the first sensor; and adjusting the calling frequency of the first sensor according to the ultraviolet light intensity. The user is more concerned with the receiving amount of strong ultraviolet radiation (such as U _Vi is more than 5), so that the calling frequency of the first sensor can be dynamically adjusted according to the ultraviolet intensity detected by the first sensor, the power consumption of the equipment can be effectively reduced, the endurance of the wearable equipment is improved, and the low-power consumption long-time continuous monitoring is realized. As shown in table 1, the lower Uvi, the lower the call frequency.

TABLE 1 calling frequencies of first sensors corresponding to different ultraviolet light intensities

The processor is specifically configured to obtain a core body temperature of the user according to the first temperature and the second temperature if the ultraviolet light intensity is less than the first threshold. Specifically, the processor calculates the first temperature and the second temperature by adopting a multiple linear regression model to obtain the core body temperature.

The embodiment of the invention determines the current ultraviolet radiation degree by utilizing the ultraviolet light intensity, and when the ultraviolet light intensity is smaller than the first threshold value, the user is indicated to be in a low ultraviolet radiation scene, and the influence of the ultraviolet light on the core body temperature of the user is smaller. Therefore, the core body temperature can be calculated without considering the ultraviolet intensity, and only the ambient temperature and the skin temperature of the user are considered.

The first threshold is a preset ultraviolet intensity threshold.

Wherein the multiple linear regression model is T _c＝f(T_E,T_S, c 1), c1 is a constant, T _E is a first temperature, T _S is a second temperature, and T _c is a core body temperature.

The processor is specifically configured to obtain a core body temperature of the user according to the ultraviolet light intensity, the first temperature, and the second temperature if the ultraviolet light intensity is greater than or equal to the first threshold. Specifically, the processor calculates the ultraviolet light intensity, the first temperature and the second temperature by adopting a XGBoost model to obtain the core body temperature.

When the ultraviolet light intensity is greater than or equal to a first threshold, the user is indicated to be in a high ultraviolet radiation scene, and the ultraviolet light has a larger influence on the core body temperature of the user. The intensity of uv light needs to be considered in calculating the core body temperature.

Wherein XGBoost is T _c＝f(T_E,T_S,U_VI, c 2), c2 is a constant, T _E is a first temperature, T _S is a second temperature, U _VI is ultraviolet light intensity, and T _c is core body temperature.

Under the irradiation of strong ultraviolet radiation, the temperature of the head skin of the human body and the environmental temperature of the environment where the intelligent glasses 20 are positioned are greatly increased, but the rising amplitude of the core body temperature is smaller due to the body temperature regulating mechanism of the human body. Under the condition that the ultraviolet radiation intensity is not considered, the core body temperature of the human body is calculated by only using the skin temperature, the ambient temperature and the like, and great deviation can occur, so that wrong abnormal body temperature reminding is caused. Under the condition of strong ultraviolet radiation, on the basis of skin temperature and ambient temperature, the coupling introduced by ultraviolet intensity is added, so that accurate core temperature calculation can be realized, and an accurate result is provided for a user. Therefore, the ultraviolet intensity is compared with the first threshold value, and the detection models of the core body temperature are respectively built according to the radiation intensity scenes, so that the core body temperature detection accuracy can be effectively improved. The calculation method of the core body temperature under different ultraviolet radiation scenes is realized.

The processor is specifically configured to prompt the user for ultraviolet protection based on the ultraviolet radiation. Specifically, if the ultraviolet radiation is less than or equal to the second threshold, indicating that the user receives less ultraviolet radiation, the processor does not perform ultraviolet protection prompt; if the ultraviolet radiation is greater than the second threshold, indicating that the user receives more ultraviolet radiation, and the processor prompts the user for ultraviolet protection according to the ultraviolet radiation.

In an embodiment of the invention, the second threshold is an ultraviolet radiation threshold.

Optionally, the second threshold is set by a user. Before the processor obtains the ultraviolet light intensity collected by the first sensor 251, the first temperature collected by the second sensor 252 and the second temperature collected by the third sensor 241, the processor is further configured to obtain the second threshold in response to a user's modification operation on the target control for displaying the second threshold.

Optionally, the second threshold is a personalized threshold corresponding to the physiological parameter of the user. For example, the mobile phone generates a personalized threshold according to the physiological parameters of the user, and then the smart glasses acquire the personalized threshold from the mobile phone as a second threshold. Optionally, the mobile phone detects the roughness and aging degree of the skin by photographing the face or the skin of the arm of the user to generate the personalized threshold. Optionally, the user can manually change the personalized threshold according to the requirements of daily life and working scenes of the user.

When the ultraviolet radiation received by the human body exceeds a second threshold value, the user needs to be reminded of the protection in time. Due to the difference of physique of people and the different bearing capacity to ultraviolet radiation, the second threshold value can be adaptively set according to the skin state, the roughness and the like of the user, so that the effect of setting personalized parameters is achieved. FIG. 4 is a schematic diagram of a mobile phone generating personalized thresholds according to physiological parameters of a user in an embodiment of the invention, wherein as shown in FIG. 4, the mobile phone displays an ultraviolet radiation personalized setting interface, and firstly prompts the user to open a camera to provide photos of the face and the upper arm; after providing the face and upper arm photos for the user, displaying an interface in parameter analysis, performing parameter analysis on the face and upper arm photos by the mobile phone, identifying physiological parameters such as skin roughness, aging degree and the like of the user through the face and upper arm photos, and comprehensively analyzing according to the physiological parameters of the user; after the mobile phone parameters are analyzed, the mobile phone displays the generated personalized reminding parameters, wherein the personalized reminding parameters comprise the radiation reminding duration corresponding to different ultraviolet intensities. The personalized threshold is the ultraviolet radiation under different ultraviolet radiation indexes and corresponding radiation reminding time lengths. In addition, the mobile phone can also prompt the user to manually adjust the radiation reminding duration, so that the aim of changing the personalized threshold is fulfilled. The embodiment of the invention provides the capability of individually setting the second threshold value, meets the requirements of more widely used people, for example, users working outdoors in high ultraviolet radiation for a long time can adjust the second threshold value according to the self requirements.

The processor is specifically used for carrying out temperature protection prompt on a user according to the core body temperature.
